Be it known that I, FREDERICK llncnnaxx, of Whitefish Bay, in the county of Milwau- Y kee and State of Wisconsin, have invented a transmitting messages telegraphically from one station by continuous conductor or line wire to a distant station and for receiving in essages from that distant'station. There may be several instruments in the line or circuit. D nplicate instruments are used at the several stations. Synchronous movement of the several instruments is secured by clockwork and by regulation of the instruments by the operators.

My invention relates to the improvements in the instrument and related mechanism and devices for transmitting messages by electricity and for receiving messages similarly invention.

In the drawings, Figure 1 is atop plan View of the mechanism and devices embodying my Fig. 2 is a side elevation of the same mechanism and devices shown in Fig. 1. Fig. 3 is a longitudinal vertical section of the mechanism shown in Fig. 1, parts being broken away and other parts omitted forconvenience of illustration.- Thus on the cylinder in this figure only four pins or teeth are shown, being those on the cylinder in the same diamctrical plane and adapted to be contacted by a single key. Fig. 4 is a view of the cylinder. regulating device and a detail of the paperfeeding mechanism. Fig. 6 is an elevation showing a detail of the paper-feeding meche Fig. 5 is a detail of a movementanism, the view being at a right angle to the 10, is of such suitable size and form as adapts I it for supporting operative parts of the mechanism. rod 13, parallel with the bar 12, are secured to and supported on the frame 11 and are A transverse bar 12 and a transverse electrically insulated therefrom by interposed blocks or pieces of insulating material 14: let.

A number of keys 15, each being preferably a fiat metal bar, are pivoted at their rear extremities at little distances apart on the rod 13, that passes transversely through them, the keys at this end being separated from each other conveniently by metal spacing-rings '16 on the rod 13 between each two of the keys.

For convenience in use each of these keys is provided with a finger-button 17, on which is marked a letter of the alphabet or some l'igure or character desired in telegraphing and corresponding with the same letters, figures, or characters on the type-wheel hereinafter described. 1

- For the purpose of illustrating my invention I have in the drawings herewith shown keyshaving buttons marked only with the letters of the alphabet; but it should be n11- derstood that a greater number of keys can be employed to be marked with figures and characters or that the few keys shown in my drawings could be marked with other characters than letters, the type-wheel being provided with corresponding figures or charactors. The front free extremities of these keys 15 enter and are movable in slots forming ways therefor in the bar 12, whereby the keys are guided in their slight movements. Small coiled-wire springs 18, inserted in sockets therefor in the barli, are adapted to support the free ends of the keys'yieldingly in normal position. An elastic inctalfingje'r l 9, secure-d ture in front of said electromagnet mcunted to the'perip'hery; of the wheel provided with a medially disposed aperture therein, guides on the'guardat each side respectiy'ely 0fthe aperture for receiving and guiding a paper strip, and a hammer adapted tobe struckagainst the strip of paper opposite the aperture in the guard and argainsta typeon the wheel. v v 8. In a printingrtelegraph, the'cornbinationof 'a. frame, a power-rotated cylinder having pins in its perimeter, a type-wheel on the axle of ,the cylinder, a ratchet-wheeler; the axle of the cylinder, and abendnlum-eseapernent engaging the ratchetewheel and provided with an adjustable weight on its pendulum.

9.- In a printing-telegraph, the ccmbination of a cylinder provided with key-contacting teeth, a. type-wheel fixed on the axle of the cylinder, a ratchet-wheel also fixed'on theexle of the cylinder, an es'capement intermittently engaging and releasing the ratchet-Wheel, a

weight-actuated drum, and gear interposed between and con necting the drn in operatively I with the cylinder.

In testimony whereof "I a'flix iny signeturc in presence of two witnesses. V FREDERICK HACIIMANN v lvitness esz I V v G. T. BENEDICT,
